user validation_errors(); in smarty template

I fix this problem, I created this smarty's plugin that it can read the function

functions.validation_errors.php

PHP Code:

<?php

function smarty_function_validation_errors($params,&$smarty) {
if (!function_exists('validation_errors')) {
//return error message in case we can't get CI instance
if (!function_exists('get_instance')) return "Can't get CI instance";
$CI= &get_instance();
$CI->load->helper('form');
}

return validation_errors(); 
}
?>
